Maps each row to a test named test_{costBounded|defended|knownGap}_{desc}. Rows covered: 1 cost-bounded: Sybil no-participation (unassigned agg, S2 non-participant) 2 cost-bounded: Sybil seat capture cost = k * MIN_STAKE 3 defended: S5 recidivism escalation fires on threshold-th miss 4 knownGap: auditor bloc inflated scores in S3 shadow mode (no slash) 5 knownGap: T1 wrong CID persists post-dispute; honest dissenter slashed 6 knownGap: dual-role cross-registration (agg + auditor, same GI) 7a knownGap: owner rejects dispute (resolveDispute=false) — bond forfeited 7b knownGap: owner suppresses via settleRecomputation(false) — bond forfeited 7c knownGap: bond locked forever when owner never resolves 8 defended: dispute-seed subgroup is deterministic; re-lock reverts 9a cost-bounded: inflated score with odd reveal count — outlier can't shift median 9b cost-bounded: even reveal count — colluder moves median halfway 11 knownGap: per-slasher S5 ring evasion across two task contracts --- foundry/test/P3Adversarial.t.sol | 845 +++++++++++++++++++++++++++++++ 1 file changed, 845 insertions(+) create mode 100644 foundry/test/P3Adversarial.t.sol diff --git a/foundry/test/P3Adversarial.t.sol b/foundry/test/P3Adversarial.t.sol new file mode 100644 index 00000000..89811154 --- /dev/null +++ b/foundry/test/P3Adversarial.t.sol @@ -0,0 +1,845 @@ +// SPDX-License-Identifier: UNLICENSED +pragma solidity ^0.8.28;

Fix 2 (row 8): prove subgroup determinism via vm.snapshotState/revertToState (same locked seed, different timestamp → same assignees). Add a separate test for the post-expiry re-anchor path (>256 blocks → DisputeSeedReanchored, then a second lockDisputeSeed succeeds). Fix 3 (row 2): measure real T1 seat capture from the drawn batch; assert sybilSeats <= k with a logged count. Fix 4 (rows 3, 1c): replace slashPartial pranks with three complete real GIs via new _runOneGIWithMiss helper. Row 3 adds the 4th-registration-reverts check (TC_AggregatorNotActive after S5 jailing). Row 1c becomes a dedicated test_costBounded_sybilNoParticipation_s5OnThirdGI test using the same helper.

It does +not yet add a Docker runner, a smoke workflow job, or complete seven-contract +deployment assertions. The Python CI job still selects `not integration`. +Full lifecycle wallet switches and later phases are not verified by this change. + +In a disposable checkout/environment, isolated mode requires absolute +`DIN_TEST_TMPDIR` and `DIN_TEST_RESULTS_DIR` paths. Scratch must not already +exist; results must be outside scratch. The harness refuses checkout dotenv +files, uses a local-only subprocess environment, creates a fresh offline Kubo +repository, and rejects occupied ports without terminating their processes. +Only newly started process groups are stopped, including when setup fails +before fixture yield. Startup logs remain in the external results directory. +Both compiler paths remain enabled at this foundation stage; the Foundry-only +selection will accompany the later smoke runner. + +Isolated bootstrap generates accounts 0/1 from the public Anvil mnemonic at +the disposable package's `dincli/config/accounts.json`, refuses an existing +file, and removes the generated file on teardown. `connect-demo-wallet` reads +this file; setting `ETH_PRIVATE_KEY_N` alone does not supply demo accounts. +Existing manual runs must provide their own public account file with enough +entries for the chosen phases. Real-wallet commands deliberately reject demo +wallets and must not be substituted during bootstrap. + +The focused tests below exercise startup failures, process ownership, +interruption, account setup and retained evidence without launching Anvil or +IPFS, compiling contracts or contacting a chain: + +```bash +python -m pytest tests/test_integration_demo.py \ + tests/test_integration_services.py tests/test_integration_harness.py -q +``` + +Isolated mode is a harness setting, not a container or a guarantee that an +arbitrary checkout is disposable.

The manifest is fetched from IPFS by a CID the model owner controls, so a malicious model owner could have any client/auditor/aggregator who interacts with their model overwrite an arbitrary file (e.g. ~/.ssh/authorized_keys) on their own machine -- confirmed with a concrete exploit walkthrough in the issue. The one existing path-side defense (_normalize_path in dincli/services/ipfs.py) only logs a warning for four hardcoded system directories and never blocks the write. Fix: a new resolve_manifest_path(base_dir, manifest_path) helper (dincli/cli/utils.py) rejects an absolute manifest_path outright, and rejects anything whose resolve() isn't contained in base_dir.resolve() (Path.is_relative_to) -- raising ManifestPathEscapesBaseError rather than silently re-anchoring. resolve() follows symlinks, so a symlink placed inside base_dir pointing outside it is caught the same way; that's deliberate. Every manifest-driven call site now goes through it instead of a raw `/` join: dincli/cli/client.py, dincli/cli/aggregator.py (x2, T1 and T2), dincli/cli/auditor.py (x3), dincli/cli/modelownerd/{aggregation, auditor_batches,gi,model (x2)}.py, and the task-contract artifact path in dincli/cli/context.py (falls back to the bundled ABI on an escape, same as every other malformed-manifest case there, rather than raising). ensure_file_exists itself also gained a containment check as a backstop -- a new base_dir kwarg (defaulting to CACHE_DIR when the caller doesn't have a tighter, model-specific base on hand), so a future call site that forgets resolve_manifest_path still can't write outside it. Tests (tests/test_manifest_path_traversal.py): the helper itself (relative-ok, absolute-rejected, ".."-rejected, symlink-escape- rejected), ensure_file_exists's backstop (explicit base_dir and the CACHE_DIR default), one real call site per role plus the artifact path -- each invokes the actual CLI command function with a malicious manifest and asserts ManifestPathEscapesBaseError fires before ctx.obj.ensure_file_exists (the actual download/write) is ever reached. Break-then-fix shown (reverting one call site makes its test fail, restoring it passes again). Two of the per-role tests (aggregator, auditor) can't run in this sandbox's Python 3.10 -- dincli.cli.aggregator/auditor both import dincli.cli.dintoken, which uses a 3.12+ nested-quote f-string that fails to parse here (pre-existing, unrelated; same reason tests/test_dintoken.py is already excluded everywhere else). Written and logic-reviewed against the same pattern the other two (verified) per-role tests use. pytest -m "not integration" otherwise green: same 16 pre-existing environment-only failures as before (py-cid version mismatch, test_integration_marker) plus these 2, no new regressions (199 passed, up from the prior baseline by the 12 new passing tests). Documentation/public/manifest.md's `path` field description now says paths must be relative and stay inside the model's directory.

The fallback was also too wide for participants, since it allowed writes into any model's cache dir. base_dir is now required (keyword-only) on both ensure_file_exists and load_custom_fn, and is always the root of the workflow the file belongs to: - get_model_base_dir(model_id) = CACHE_DIR//model_ for clients, auditors, aggregators, and the model owner once the model is registered - the new get_task_dir(coordinator) = cwd/tasks// for the model owner while preparing the task Every caller passes one of the two. The inline cwd/tasks and CACHE_DIR joins in modelownerd/{model,aggregation,auditor_batches} and system.py now use these helpers. Tests: - a missing base_dir is a TypeError - a participant can't write into another model's dir - regression: the real load_custom_fn on a cwd task dir outside CACHE_DIR dincli-testing-guide's sibling-module example now uses resolve_manifest_path and passes base_dir.

Owner block-picking of the seat shuffle is closed by the H-2 fix: the seed is fixed at a block not yet mined when it is anchored, and batch creation reads the stored seed (`test_createAuditorsBatches_timingIndependent` / `test_autoCreateTier1AndTier2_timingIndependent` in `SecurityFindings.t.sol`). Residuals remain (BL-26): the owner can decline to lock a seed they dislike and let it re-anchor after the ~256-block `blockhash` window (a repeatable re-roll while nobody else locks — aggregator/auditor dincli now locks the seed from the validator side to narrow this), and a validator can unstake between lock and batch creation to reshape the active pool. The seed also trusts the sequencer not to grind `blockhash` (TA-4).
